Anti-phospholipid Syndrome & Aspirin

I've lost four babies in less than four years, one with my ex and three since then. It's a long, complicated history. When I had my most recent miscarriage two years ago my doctor suggested taking a baby aspirin every day as a means of increasing blood flow to the embryo. She said I have no problem getting pregnant but I can't STAY pregnant for some reason. Without explaining it in detail she just suggested the aspirin and told me to call her the minute I realize I am pregnant because she will want to watch me very closely. That was more than two years ago and we haven't even had a "scare" since. We can't afford to go forward with fertility treatments right now so I decided to just do some more research. 
I was doing some research on blood clots because I've had heavy clotting during my periods. I ran across a book in which a woman discusses her struggle with numerous miscarriages. Her doctor also suggested baby aspirin at first, but she was also instructed as to the exact reason and diagnosis that triggered that suggestion. My doctor didn't explain anything to me so I kept reading. She was diagnosed with Anti-phospholipid Syndome (APS). It's an immune disorder where your antibodies attack your own blood cells, causing clots. This may not be my problem. I'm just curious. Has anyone else dealt with this? I wonder how common it is. There isn't as much info out there on it as I thought would be.  
The woman in the book was diagnosed in the early 2000's. She had to eventually move from the aspirin and inject herself multiple times per day in the stomach with some kind of anti-coagulant  to get pregnant, continuing the injections throughout her pregnancy
I don't have insurance. I will have in six months when it kicks in at work. I doubt it will cover this. I am concerned with the cost and want to hear from women who have dealt with this sort of thing. Thanks in advance, ladies!
